    Temperatures and fps are stable, but since it is essentially overclocking. Does it mean my gpu is screwed within the next 5-6 years? I am pretty sure the only thing that will brick a gpu is temperature and voltage but according to my voltage curve i essentially OCed and undervolted (capped voltage to .925 V) as opposed to the original voltage being capped at around 1 V

    Correct, the wear on the GPU and other components is temperature and voltage. So overclocking by locking the voltage won't increase wear if the temperatures are under control, equal to or lower than stock.
    Since we can't undervolt the pascal GPU like we do for the CPU, essentially what is being done with the curve is finding the maximum clock for that particular voltage, so in other works the most efficiency for performance per watt.

    I have been a long time lurker on this forum and have recently purchased a Razer Blade 14 2017.

    This guide has been extremely helpful however I have a question: is there a way to undervolt the igpu within the bios? I don't believe it was explicitly stated unless I missed it.

    I'm curious because I was looking through the bios file and under Setup > Advanced > Overclocking Performance Menu, there is a 'GT' section which I assume to be the integrated graphics as the 'Graphics Turbo' controls the integrated graphics on the current intel processors. Additionally, it seems that it is possible to activate, in the same way the core undervolt is configured including a section for a 'GT Voltage Offset.' Has anyone tried this?

    Why do you want to uV iGPU? Intel HD630 is inside the CPU, uVolting CPU means also uVing right? For UVolting it through Bios you need to flashing the original Bios, @figrin1 show a tutorial link from @fer.geraci on YouTube. Note flashing your original Bios could brick your system.
    Not tried yet but I think it’s graphics card frequency, is it in MHz/on off options? There’s a lot shortages on bios that could misleading the interpretation, some said the manufacturers only words, like “GT“ for “grand turismo“ that means speed.

    Yes, you can undervolt the iGPU in the GT section....sliced and unsliced. You shouldn't undervolt very much though, I would say around 50mV.

    I haven't tweaked this because I haven't seen anyone else who has. But if you decide to go for it, I'd be interested to hear whether it makes a significant difference in CPU temperature/performance

    I see, i just want to show what is the impact of uV iGPU, because i don’t really understand the purpose of it since it’s inside CPU, so it’s enough to uV CPU for better thermal. Is it now undervolting on trend? What the next, SSD;)

    Thank you for all of your quick replies!

    I am exploring the possibility of undervolting the igpu via the bios because I received better idle/load temps using TS and undervolting the core/cache and integrated graphics. At the moment, I have undervolted the core/cache in the bios and still return decent temps but still roughly ~8C warmer than when I had a combined stable undervolt between the cpu/cache/igpu.

    As you already know, the igpu exists in the same housing as the cores/cache/sa..etc. Undervolting the core is simply just that, there are still other components within the CPU that are receiving higher voltage and thus contributing heat. Undervolting the igpu theoretically decreases operating temperatures while mitigating the marginal performance decrease of the CPU a higher core voltage offset would incur in order to achieve the same temperatures.


    I agree, I will definitely be very conservative while doing so. I was stable with -60mV but I'll play it safe and use -50mV.

    I'll let you know once I do.[/QUOTE]

    This is a cool image, for anyone who's wondering how a CPU is separated into distinct parts: upload_2018-2-16_11-47-36.png

    Hey, thanks for all of this info. Would you mind sharing some of the documentation you mentioned about Windows preventing processors from entering C8 states? I haven't been able to find it myself.

    I've done the check you recommended using Throttlestop, but the instructions are a little unclear to me. You say "see if your C-states go higher than C2", but then you say to install the driver if there's no activity in C8. What if there's activity in 2 through 7 but not in 8? Would like to some more clarity about what exactly indicates if a system is affected by this issue.
